` Serial I'No. 346,436.

To all whom it may concern:

Be it known that I, ETI-IAN I, DoDDs, a citizen of the United States,residing at Pullman, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Dumping-Cars, of whichthe following is a specification.

My present invention has for its object the improvement of dumping carswhereby the lading may be readily and completely unloaded whenthedischarging doors are opened. To accomplish this result the car-body i'smade so as to have a bottom opening larger than its top, the end wallsbeing inclined inwardly and upwardly to assist in the dischargingoperation. With such a construction, a'moist lading, which ordinarilyhas a strong tendency to adhere or stick to the car-body walls can becompletely discharged, the weight of the load being used, as will bereadily understood, to cause it to leave the walls and drop through thedoor openings.

In the accompanying drawings, I have illustrated two desirableembodiments of my invention, and on the various views like referencecharacters refer to the same parts throughout.

Figure l is a plan view of the preferred embodiment of my invention;Fig. 2 is a partial side elevation and partial longitudinal centralsection of the dumping car shown in Fig. l; Fig. 3 is a vertical sectionadjacent to one of the body holsters, on line 3-3 of Fig. l; Fig. 4 is avertical cross section on the line 4-4 of Fig. l; Fig. 5 is a plan viewof a modified form of car; and Fig.v 6 is a partial side elevation andpartial longitudinal section of the car shown in Fig. 5.

Referring first to the car illustrated in Figs. l to 4, inclusive, itwill be observed that the car underframe includes the usual channelcenter sills l0-l0, channel side sills ll-ll disposed with their flangesextended outwardly, body bolsters 12-12 and end sills 13-13. Thecar-body through which the center sills pass, and which is locatedwholly within the side sills, comprises the side plates 14, which arevertical and parallel, and whose end edges 15-15 converge upwardly.These side plates, which are preferably made of sheetmetal, are riveteddirectly to the webs of side sills ll, as is clearly shown in Fig. 4,and on their inner surfaces are provided with the upright angle stakes16, to the inwardly-projecting legs of which are attached the ends oftransverse channels I7, which act to tie together the two sides of thecar. Centrally disposed transversely of the car-body, there is providedan I- beam 18 connected in any convenient manner to the side walls. Aswill be readily understood from an inspection of Fig. 4, thesetransverse beams 17 and 18 are omitted between the center sills, butbetween the latter I nevertheless employ any suitable number of channelspacers 19. In order to deflect the lading from the center sills, Iinclose that portion of them Within the car-body inside of a hood 20having an oppositely-inclined top surface to direct the lading to eitherside of the center sills, as will be ovbious from an inspection of Figs.l and 4. Each end wall of the car-body comprises a central portion .orplate 2l substantially rectangular in shape and upwardly inclinedinwardly, and at each side of this central plate or endwall portionthere are provided supplemental corner plates 22, which are alsoinwardly inclined, and which connect the edges l5 of the side walls tothe adjacent edges of the central end-wall plates 2l. As is usual inAdumping cars, I provide a coping angle-iron 23, which extends aroundthe top edge of the walls forming the car-body. In order to prevent thisbody from shifting longitudinally and in order to brace the samelengthwise, at each end there is used a pair of channel braces 24, whichat their upper endsare fastened to the body and at their lower ends areriveted to the outer faces of the channel center sills. Substantiallythe whole bottom of this car is composed of the hinged doors 25, hingedat the points 26 and operated by means of the chains 27 passing oversheaves 28, the chains being adapted to be wound on and paid out from adrum 29 at one end of the car. When in closed or horizontal position,these doors form a substantially fiat and Hush bottom for retaining thelading in the car, but when the drum 29 is operated to pay out thedoor-controlling chains 27, the doors drop so as to discharge the load,the latter readily dropping away from the inclined surfaces 2l and 22.Owing to the fact that the end walls slope inwardly, the weight ofthe'lading acts to free the same from the inner surfaces of the walls,whereby substantially all of the load is discharged and none allowed toadhere to the walls. When a moist lading, such as ore, is used in a carwith vertical sides and ends, or in a car having downwardly-inclinedsides or ends, the lading adheres to the walls sufficiently so that insome cases it arches over the door openings, and can only be removed bymeans of a bar or similar tool to break up the arch. Although I havedescribed this car as having center sills and side sills, it will beapparent that either may be omitted, provided the side walls of the carare made sufficiently strong to form plate girders to support the bodyand load,

The modified structure shown in Figs. 5 and 6 is substantially likelthat described above, with the eX- ception of the end walls. In thiscar these end walls,

instead of being each made of three parts, are composed oi only twoparts 30 and 31, disposed at an acute angle With relation to oneanother. 1t will be noted that this modification is only slight, andthat substantially all the.advantages of the form o car shownv in Figs.1 and 2 are found in the car illustrated in Figs. 5 and 6, since theseend-Wall portions 30 and 31 are inclined inwardly and upwardly, as inthe construction described above.

This application is a division oi my former application Serial No.215,492, for steel car construction, AFiled July 6, 1904, to which4reference is made.

To those skilled in the art it Will be apparent that Various minormechanical changes may be made in the structure shown and describedherein Without departing from the substance oi my invention orsacrificing its advantages.

I claim:

1. ln a railway car, the combination of a car-body, the end walls ofwhich are composed of a plurality of parts disposed at an angle to eachother and each inwardly inclined upwardly, and one or more doors to openand close the bottom of said car-body, substantially as described.

2. In a railway car, tbe combination of a Carmody, each end wall ofwhich has a central portion upwardly and inwardly inclined and a portioneach side thereof similarly inclined and joining said central portion tothe side walls of the car, and one or more doors to open and close thebottom of said car-body, substantially as described.

In a railway car, the combination of a car-body hav ing' verticalparallel side Walls, the end edges of each of which converge upwardly,said body having end walls each composed of a rectangular centralportion upwardly and inwardly inclined and a portion each side thereol`similarly inclined and joining the ond edges of the side walls with theadjacent edges of said central portion, and one or more doors to openand close the bottom of said car-body.
